Vista x64 slow net connection - Antivirus responsible

[0iD]

My net connection slowed to a crawl recently and after much digging it turned out to be my antivirus, NOD32. Uninstalled & speeds shot up. Tried AVG free, same story, connection dropped fron 2400kb/s to about 150. So uninstalled & connection speeds went back to normal. Tried just disabling the resident shield, but no change.

Odd thing is, this didn't happen till I swapped provider & router.

I think it was one of the more recent updates, it does it with kaspersky as well.

Does windows mail really slow down as well, just from navigating through the preview of emails in your inbox?

Anyone know a solution to this?

I want to install Vista 64 soon, and I use NOD32. But I don't want to lose internet speed.

Mine doesnt with Kaspersky so maybe im just lucky. Btw...i have installed all the MS updates aswell.

I dunno what could be the problem as CLunk has mentioned this already. Maybe it is Vista...or maybe it isn't. Surely if it was though, everyone would be having these issues.

Its weird that its happening across more than one program. Looks like they changed something in Vista that the software makers dont know about, or that its a bug in Vista only effecting some systems.

Have you guys got the windows firewall enabled?
Try knocking it off if so, just for testing

I have. Maybe thats why.
I will knock it off later and re-install the Kaspersky one and try that to see if i can replicate this slow down.
